A kit with both a hand-held meter and noise dosemeters offers:
For occupational noise measurement either a dosemeter or a sound level meter can often be used to achieve the same result: the measurement of noise and calculation of a worker's daily noise exposure, or LEP,d. In some workplaces it is better to use a hand-held sound level meter, while in others the best option is to use a noise dosemeter mounted on the worker. Here are some guidelines:
The Combination Kit from NoiseMeters is supplied in a tough Peli Case that protects the dBadges, sound level meter and accessories. More details...
Use a dosemeter when the worker is moving around continuously, or between many different locations. A dosemeter is also a better option when the worker is in a location that makes the use of a hand-held meter difficult, such as confined spaces or in the cab of moving machinery. Finally, a dosemeter can take much less time to use as you do not have to follow the worker around while making measurements. This is particularly important when monitoring the noise exposure of large numbers of workers.
Use a sound level meter to make quick and accurate spot-checks of the noise levels. A hand-held meter is ideal when people are only working at a few fixed locations - you measure at each and calculate the exposure as a Time Weighted Average. When the noise levels are particularly high a more advanced meter should be used to assess the level at the ear when wearing hearing protectors. The greatest benefit when using a sound level meter rather than a dosemeter is that you are present when the noise occurs, so you can assess if the sound levels are representative of normal operations.
We can create many combinations of sound level meter and dosemeter but the following are the most popular, covering most applications. If you want something different then just email us on firstname.lastname@example.org.
